S&P 500 (SPX) Day Trading Strategy
Revision Date: February 6, 2026 | Effective: January 2, 2026

1. Strategy Overview

This is an income-focused strategy centered on selling 0DTE (Zero Days to Expiration) options premium. By entering the trade during the Opening Range, we capitalize on peak volatility and time decay (Theta). This is a passive exit strategy: once the trade is entered, it is held until the market close for cash settlement.

• Asset: S&P 500 Index Options (SPX Weeklys/0DTE).
• Structure: Vertical Credit Spreads (Out-of-the-Money).
• Philosophy: Hands-free execution; disciplined 2:1 Risk/Reward ratio.

2. Core Trading Rules

• Entry Timing: Optimal entry occurs between 9:30 AM and 10:30 AM ET to capture peak volatility; all trade executions must be completed no later than 1:00 PM ET.
• Technical Entry: Use intraday charts and a Delta Filter to identify high-probability OTM (Out-of-the-Money) strikes.
• Frequency: Maximum of one trade per day.
• Exclusions: No trading on market half-days. Fed/FOMC days are acceptable.
• No Manual Exits: Positions are held until expiration; no intraday stop-losses or profit-taking orders are used.
• No Overnights: All positions settle to cash at 4:00 PM ET.

3. Risk & Capital Requirements

The following models define how much of your total account equity is assigned to the Maximum Loss of a single trade.

Model	Risk Level	Minimum Account Capital	Profit Target (on Capital)
R5	5%	$10,000	2.5%
R10	10%	$5,000	5.0%
R20	20%	$2,000	10.0%

Regulatory Note: A minimum of $2,000 in cash or assets is required by federal regulations to maintain a margin account for options spreads.

4. Mathematical Exit Strategy (1:2 Ratio)

Because this strategy removes manual exits, the 1:2 Profit-to-Loss ratio must be “baked in” at entry by selecting the correct spread width and credit.

• The Goal: Collect a credit equal to approximately 33% of the total spread width.
• Example ($5.00 Wide Spread):
  • Sell Spread for: $1.65 Credit (Max Profit)
  • Collateral Risk: $3.35 (Max Loss)
  • Ratio: 1.65 : 3.35 (Approx. 1:2)

Settlement Outcomes:

1. Full Win: SPX closes outside the short strike. Contracts expire worthless; you keep 100% of the premium.
2. Full Loss: SPX closes beyond the long strike. The loss is capped at the spread width minus the credit collected.
3. Partial: SPX closes between strikes. The account is debited based on the final settlement price.

5. Strategy Maintenance

• Compound Interest: Profits should be reinvested to allow for scaling of contract sizes based on the selected R-Model.
• Discipline: Strategy success depends on the law of large numbers; maintain a hands-off approach and allow all trades to reach the 4:00 PM cash settlement without manual interference.
